1. APPLICATION Retail scale WTC type is a perfect weighing device for application in small and standard trade. power supply by inbuilt batteries allows for application on location, with no access to power supply, like market place. Scale is equipped with three backlit LCD displays enabling readout of result by person standing in front of it. Scales have plastic casing and stainless steel pan.
G. In case of failure, immediately disconnect scale power supply; H. Devices that are to be withdrawn from usage should be utilized according to the law. I. On finish of working day, turn off the scale with switch . additionally, for safety and power saving purposes, unplug the scale from A/C mains. J. Dead batteries (accumulators) should be utilized according to the law; 3. WARRANTY CONDITIONS A.
4. DIMENSIONS Dimensions of scales in WTC/S series Dimensions of scales in WTC/SW series 5. SCALES ASSEMBLY Remove the scale from factory packaging and place the scale on flat and hard surface far from heat sources and next: • Pull out the transport protections (applies only to scales with max.
• Install the pan and the pillar (WTC/SW scales) according to below drawing: Assembly of scales WTC/S series Assembly of scales WTC/SW series Caution: 1. During assembly of the pillar in the WTC/SW scale put attention not to “cut” display tape. 2. Before starting the weighing remove (tear off) foil protecting scale pan. 6. STARTING AND OPERATION • After assembly (see point 5 of manual) place the scale on flat and hard surface far from heat sources. • Scale should be levelled by turning regulation feet.
• Turn on the supply with switch , • After turning on the supply, wait until scale test is finished, • When scale test is finished in display window mass indication equal to zero will be indicated and symbols ▼will be displayed above marks: ZERO - indication precise zero STA - weighing result is stable AC - scale power supply from external A/C adaptor • If weighing result is other than zero – press zeroing key. 7. SUPPLY Retail scales WTC series use two power supply sources.
Connect to scale A/C adaptor to recharge accumulator and restart the . device with switch 8. SCALE KEYBOARD 9. SCALE DISPLAY Display of scales series WTC/S Display of scales series WTC/SW Notice: Because functionality and use of both display types is identical, further part of instruction will be based on display of scales series WTC/S.

12. USER MENU 12.1. List of scale menu groups Menu is divided into 3 basic groups. Each group has individual name starting from capital letter P. Groups names and their contents is shown below: P1 rEAd P 1.0. P 1.1. P 1.2. P2 Prnt P2.0. P2.1. P3 othr P3.0. P3.1. Fil Fnnd Auto | | | 2 OFF On Prn bAud | | StAb 9600 bL bEEP | | Auto YES 12.2. Moving in user menu User moves in menu by means of scale keyboard. 12.2.1.
12.2.2. Return to weighing function Inserted changes in scale memory will be saved after return to weighing with procedure of saving changes. Press several times key until display indicates message . When question is indicated press : – to to resign from inserted changes. confirm changes or After pressing appropriate key, scale will return to weighing. 13. WEIGHING Place on the pan weighed load.
After placing the load, scale display will indicate net mass. Tarring can be done many times in full measuring range of scale. While using the tare function, pay attention not to exceed max measuring range of scale. After removing load and packaging indication equal to sum of tarred masses with minus sign will be displayed. Notice: Tarring process can not be carried out when there is negative mass value or zero mass value on scale display.
14.1. Setting the filter level Procedure: • Enter to submenu according to point 12.2 of manual, and next: 0 - 4 - filter level depending on environment al conditions Return to weighing: See – point 12.2.2. – return to weighing. Notice: The higher filter level the longer time of weighing result stabilisation. 14.2. Median filter Median filter is applied for eliminating short impulse disturbances (e.g. mechanical shocks). Procedure: • Enter to submenu according to point 12.
Fnnd Fnnd OFF - median filter operation on On - median filter operation off Return to weighing: See – point 12.2.2. – return to weighing. 14.3. Autozero function „AUTOZERO” function was introduced to ensure precise indications. This function was applied to control automatically and to correct zero indication of scale. When function is active, consecutive results are compared in fixe periods of time. If these results differ less than declared range of AUTOZERO e.g.
Example of that can be very slow loading of pan (e.g. load pouring ), in such case correction of zero indication can also correct indication of real load mass. Procedure: • Enter to submenu according to point 12.2 of manual, and next: AUTO AUTO no - autozero off YES - autozero on Return to weighing: See – point 12.2.2. – return to weighing. 15.
Transmission parameters programmed in scale: • • • • Transmission baud rate - from 1200 to 57600 bit/s Data bits - 8 Stop bit - 1 Parity control - none Value indicated by scale display can be sent through port in series to peripheral device in one of three ways: • Manual – after pressing key , • In continuous way – after function activation or after sending control command, • On request from peripheral device – see point 21.2. of manual. 15.1. Printout type Parameter enables to choose printout type.

21. COMMUNICATION PROTOCOL 21.1. General information A. A character protocol scale-terminal has been designed for communication between RADWAG scales and peripheral devices via RS-232 interface. B. It consists of commands sent from an peripheral device to the scale and a responses from a scale. C. Responses are sent every time after receiving a command (reaction for any command). D. Using commands allows users to receive some information about the state of scale and/or influence the operation e.g.
21.3.
T_A CR LF T_v CR LF - command accepted and in progress - command comprehended but tare range exceeded T_A CR LF T_E CR LF - command accepted and in progress - time limit for stable result exceeded T_I CR LF - command comprehended but currently not accessible 21.4.3.
Frame format: 1 2 3 4 5 6-14 15 16-21 22 23-30 31 32 S I space Stability mark mark mass space price space charge CR LF Example: S I CR LF – computer command S I _ ? _ _ _ _ 2 5 . 0 0 0 _ _ 1 5 . 9 9 _ 2 5 9 9 9 . 7 4 CR LF - stable display state is received immediately 21.4.5.
21.5. Manual printout User can generate printouts from scale manually when indication is stable after pressing key .
21.6. Continuous transmission Indicator has possibility of mass printout in continuous transmission. Transmission mode can be switched on with command through RS232 port (see point 21.4 of manual) or by parameter setting (see point 15.1 of manual).
22. ERROR MESSAGES Err2 - Value beyond zero range Err3 - Value beyond tare range Err8 - Exceeded time of tar ring/zeroing operation null - Transducer zero value FULL2 - Measurement range exceeding LH - Start mass error, indication beyond ±10% range of start mass 23.
